Testing begins on Perth's new Matagarup Bridge

Local workers involved in the construction of Matagarup Bridge, which will connect to the new Optus Stadium, were the first to walk across it today with the opening now just weeks away.

It's also not the only test the bridge will face.

Friday will see the start of a more controlled series of testing, referred to as 'tuning' or 'dynamic testing'. That process will allow technicians to confirm the amount of expected movement from the cables and make final adjustments.

Premier Mark McGowan and Transport Minister Rita Saffioti were among the crowd that made the journey across the bridge.

Ms Saffioti said the project has been one of the most technically difficult constructions ever undertaken in Western Australia.

"Our focus has always been on safety compliance and build perfection rather than rushing to get the bridge open, and the community will have this WA-made bridge to enjoy year-round," she said.
